Everybody knows what they know. The truth about gas around here is that it isn't all the same. And of course there are some gas stations that I personally avoid, due to the age of the tanks, and problems I have had in the past. I pulled a solid cup of rust out of a plastic 928 gas tank once. It had to come from somewhere.

Obviously, if I can buy non-ethanol premium here, it will not be the same as any other gas in the region.

As for additives, I do think that doubling the concentration could actually make a difference. You just doubled the concentration. Think about it. I don't really care about how much you know about anything. Facts are facts. How many micro grams of LSD does it take to mess you up ? Care to double that dose ? I buy from certain gas stations, because I know that they have newer tanks in good condition. I buy certain brands, because I trust that they will have the additives, and because I have read dyno tests over the years that seem to imply that certain gas brands DO make a difference.
Obviously, your mileage may vary.

Some people I don't really take seriously, no matter what their credentials are. This is simply due to knowing that there is something about their makeup that requires them to consider themselves right in every instance. IMO, that makes everything they say suspect. Sorry. Once again, double the additives is quite an increase. Anyone who says differently needs to review basic math. Are additive packages important ? MMM, could be, Rabbit, Could Be. But of course, those decisions are made at higher pay grades for obvious reasons. I don't do quantum physics. I am not a chemical engineer. I don't design additive packages. I don't second guess people who do just to save a few bucks a tankful. I can tell you that some chemical compounds will break down under certain conditions, some of which might be present in certain combustion chambers, and not in others. I also know that Nitrogen is an incorruptible element. Under certain conditions where some chemical compounds might break down, Nitrogen might in fact become more ''energetic''. That might not be a bad thing, at certain times, in certain circumstances. Consider specifically that carbon may be built up, or removed, in as small a quantity as one molecule at a time. Over time. Additives.

If you have a tuned car with a larger turbo, buy the gas it was tuned for. Don't be buying your gas all over town.

ZDDP in oil, is measured in PPM. Who needs THAT ???
